vet-Anatomy the interactive atlas of veterinary anatomy

vet-Anatomy is an interactive atlas of veterinary anatomy based on medical imaging. vet-Anaotmy has been created on the same framework than the popular award-wining e-Anatomy, but dedicated to animals, under the direction of Dr. Susanne AEB Boroffka, dipl. ECVDI, PhD.

Huesos sesamoideos palmares - Ossa sesamoidea palmaria

Descripción

In carnivores, the palmar sesamoid bones are two elongated, slightly curved small bony structures located on the palmar surface of each of the four main metacarpophalangeal joints, in the tendons of insertion of the interosseous muscles. They articulate primarily with the head of each metacarpal bone and secondarily with the palmar tubercles of the base of each proximal phalanx. Their truncated distal ends articulate by small facet with the palmar tubercles of the corresponding proximal phalanges. On digit I, there is a single proximal sesamoid bone.

They are numbered from medial to lateral, with the most medial sesamoid bone of the second metacarpophalangeal joint being sesamoid bone #1 and the most lateral sesamoid of the fifth metacarpophalangeal joint being sesamoid bone #8
